Base of a steel unit

ABSTRACT

A base for a steel unit comprises a support tube, a bottom plate, a platform and at least one girder. The bottom plate is connected to a lower end of the support tube and is installed with a plurality of retaining holes. The platform is connected to a top end of the support tube; and the platform is installed with locking holes near the four corners. Thereby, at least one girder having an end may be placed on the platform; and one end of the girder is locked to the locking holes of the platform. Therefore, a preferred shock-proof ability is achieved so that the elevated floor having a better shock tolerance and safety of the structure is improved.

FIELD OF THE INVENTION

[0001] The present invention relates to a base for a steel unit having shock-proof ability as the girders are locking to the top plate of the base; the girders of the present invention would not protrude out, screws would not loose, and the girders would not release from the base as earthquake occurs, moreover, the girders would not possibly bend so that the elevated floor has a better shock tolerance and safety of the structure is improved.

BACKGROUND OF THE INVENTION

[0002] The prior art elevated floor 93 is disposed on girders 90 which are intersected with each'other longitudinally and transversally (see FIG. 1 and left figure of FIG. 2). The intersecting point of the girders 90 is installed with a base 91. Each base 91 is installed with a support tube 94. The upper side of the support tube 94 is installed with a top plate 92 for supporting the girder 90 in a proper height so that the base 91 may support the girder 90 and floor 83 is in proper elevation.

[0003] However, as shown in FIG. 1, the right figure of FIG. 2 and FIG. 3, in the prior art elevated floor 93, since the girder 90 is locked to the top plate 92 of the base 91, it is weak without a preferred shock proof ability. As an earthquake occurs, the girder 90 is easy to protrude up and screws are loose (see right figure of FIG. 1). The girder 90 will release from the base 91 (as right figure of FIG. 2), and the girder 90 is bent (as FIG. 3) so that the asset is lost, moreover, human lives is threatened. Therefore, the shock tolerance and safety must be considered in designing a base for a steel unit.

[0004] Therefore, there is an eager demand for a novel base for using in a steel unit, which may improve the aforesaid prior art defects.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is to provide a base for a steel unit having shock-proof ability as the girders are locked to the top plate of the base; the girders of the present invention would not protrude and screws would be not loose, and the girders would not release from the base as earthquake occurs, moreover, the girders would not possibly bend so that the elevated floor has a better shock tolerance and safety of the structure is improved.

[0006] In order to achieve the aforesaid objects, the present invention provides a base for a steel unit comprises a support tube, a bottom plate, a platform and at least one girder. The bottom plate is connected to a lower end of the support tube and is installed with a plurality of retaining holes. The platform is connected to a top end of the support tube; and the platform is installed with locking holes near the four corners. Thereby, at least one girder having an end may be placed on the platform; and one end of the girder is locked to the locking holes of the platform. Therefore, a preferred shock-proof ability is achieved so that the elevated floor has a better shock tolerance and safety of the structure is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Referring to FIG. 4, the base for a steel unit of the present invention is illustrated. The base includes a support tube 10, a bottom plate 20, a platform 30, a top plate 40, and a girder 70 (as shown in FIGS. 5 and 7). The support tube 10 is a hollow round tube. The bottom plate 20 has a square cross section. The bottom plate 20 is welded to the lower end of the support tube 10. The bottom plate 20 serves to increase the stability for the base to support heavy object. A plurality of retaining hole 21 are installed on the bottom plate 20 for being locked to a ground through screws or other retaining element (not shown).

[0019] Further, four triangular wings 50 can be installed between the support tube 10 and the bottom plate 20. The triangular wings 50 are welded between the outer wall of the support tube 10 and the top surface of the bottom plate 20 for increasing the supporting force of the support tube 10 so as to prevent the support tube 10 from bending or deforming.

[0020] The platform 30 is a rectangular plate and is welded to the top end of the support tube 10. The center of the platform 30 is formed with a screw hole 32 (as shown in FIG. 5). Near each of the four edges of the platform 30 is installed with at least one locking hole 31. The locking hole 31 has a shape like a long slot for being adjusted.

[0021] The top plate 40 is approximately a square shape plate. The bottom thereof has a screw rod 41 vertically extended. The top plate 40 is installed on the upper side of the platform 30. The screw rod 41 in the bottom of the top plate 40 is screwedly connected in the screw hole 32 of the platform 30 so that the top plate 40 is screwedly connected with at least one hexagonal nut 42 so that the screw rod 41 can be locked to the platform 30. The top plate 40 is a selective element and can be neglected as desired (as shown in FIGS. 8).

[0022] One end of the girder 70 is placed with a platform 30 and passes through a locking hole 31 of the girder 70 and the platform 30. One end of the girder 70 is locked to the platform 30 so that an elevated floor 60 can be locked to the girders 70 arranged longitudinally and transversally. The intersecting point of girders 70 is installed with an elevated device formed by the support tube 10, bottom plate 20, and platform 30 for elevating the elevated floor 60 on the girders 70. The girders 70 support the elevated floor 60 to a proper elevation. Furthermore, a pad 80 can be installed between the girder 70 and the platform 30. The pad 80 is a plate having a proper thickness and grooves 81 are formed thereon. When the pad 80 is placed between the girder 70 and the platform 30, one end of the girder 70 can be adjusted for adjusting the horizon of the girder 70. The groove 81 may be passed through by a screw 71. By aforesaid components, a base having a steel unit is formed.

[0023] In the present invention, the top end of the support tube 10 in the base has a platform 30 so that the girder 70 has one end can be locked to the platform 30, and thus a steel unit is formed. Sine the platform 30 is connected to the support tube 10 with a larger diameter and thus has a preferred strength. The platform 30 has a larger area for steadily supporting the girder 70 and spreading the stress due to earthquake. Therefore, it has preferred shock-proof ability. In earthquake, the girder 70 prevented from protruding upwards, releasing of the screws 71, unlocking between the girder 70 and the base, and bending of the girder 70 can be prevented.

[0024] Further, as shown in FIG. 8 and 9, each of the four corners is installed with an elevated device. The platforms 30 of the four elevated device are installed with respective main post 33. The adjacent edges and opposite edges of the elevated device are firmly secured with a plurality of girders 70. The middle portion of the girder 70 has a post 77 for connecting the supporter 78 so that the supporter 78 may support the floor (not shown). By intersecting the girder structure, the force applied thereon can be effectively transferred to nearby supporters for preventing the supporters from deformation, increasing the bearing ability, and preventing the protrusion of the floor. Further, the shock is prevented.

[0025] As shown in FIG. 10, the platform 30 of the elevated device is installed with a plurality of adjustable screw holes 34. Each screw hole 34 is screwedly connected to an adjusting screw 35. The adjusting screw resists against a bottom of the girder 70. By the adjusting screw 35 to rotate and push the girder 70 to be moved along the z axis and adjust the horizon. After the adjustment is completed, a screw 71 serves to lock the girder 71 to the platform 30 of the elevated device.

[0026] Therefore, the present invention can improve the defects in the prior art, such as bad shock-proof ability as the girders are locking to the top plate of the base; the girders are easily protruded and screws are easily loosen, and the girders are released from the base as earthquake occurs, moreover, the girders possibly bend. However, all these defects can be improved by the present invention.
